Much thanks for the references, Karsten. Ditto the excellent tool library

I'm looking for an MVC framework for Swing apps. I'm thinking of

not a framework out there to expedite this.

I suggest you check out the MVP and "Presentation Model"
patterns. Just google "Organizing Presentation Logic",
and you'll get a reference to a narrative by Martin Fowler
where he motivates MVP and Presentation Model.

I've found that a good understanding of these patterns
helps every project, where in contrast other techniques
like automatic databinding can increase or decrease your
productivity.

Once you're familiar with these patterns, you may choose
a helper library or framework that follows one of these
approaches.

I provide presentation about desktop patterns and
data binding at http://www.jgoodies.com/articles/
and a free open source helper library for working
with the Presentation Model pattern in Swing:
the JGoodies Binding. But as said in the slides,
automatic data binding is a wild horse that may
be difficult to ride on.

Because I was completely unfamiliar with Matisse, and netBeans (or

How would you describe netBeans in a couple of sentences? What's the
relationship between Matisse and AWT/swing/SWT?

Matisse makes Swing objects, little classes that you can call new on,
and setVisible, and they do all your display, layout and event firing
for you.

Get NetBeans. (Get the latest one, 5.5) You don't need any plugins,
everything is there for you already. Go through the tutorial below,
it'll take about 30 minutes. If your eyes don't pop out of your head
like Rodger Rabbit, then you can safely ignore it.

there is usually a multitude of ways to do things.

here is your layout , as i think you wanted it , including resize!!
the text area really does not look too good, full length of the window, so i
have adjusted it, also this code will resize smaller, than the previous
examples and retain some semblance of what is in it.

pls note when resizing, the areas will jump about and not maintain the ratio
, i don't know how you want it but you just need to play about with the
weights for each area

Well, it works... but it's not resizable.

No, this was manually written.
Did you manually replace the include import javax.swing.* with all the
individual classes?

Anyway, if there's no solution (which would be disappointing; I'm not
think I'm asking for a lot of the layout managers) I have a backup
plan: have a resize function that manually divides the window between
the component the way I want to.

But it feels like a cop-out.

Not to complicate things but you could do this with JGoodies Forms
layout with no problem. I will build one and send to this forum.

If you can't figure out a solution using existing components and layout

Right. I just like to add that there exist layout managers
that handle huge classes of screen design, for example
the ExplicitLayout, or even better the ExplicitLayout plus
Explicit Table Builder.

I can do all my screen design with existing layout managers
- at the form level. And I write custom layout managers only
at the component level, for example to lay out combobox parts.

It seems to me that many developers think that writing
a custom layout manager is difficult; it is not.
But it's difficult to write a custom layout manager
that lays out forms that follow the MS Layout specifications
and guidelines, because it is based on Dialog Units,
not pixel, where basic Java has only pixels as unit.

Forgot to mention to change the line above to false. This will stop
displaying the red panel lines you use to determine how you want to
layout your panel. Also will stop sending System.out information on the
Forms layout debugging information.

No the actual JGoodies Forms Library (forms-1.0.6.jar) is only *48kb*.

The complete Forms zip download, from
http://www.jgoodies.com/downloads/libraries.html, is only *1.1MB*.

Also the last example, using gridbag from Steve, is still doing what
Oliver did earlier today in his example.. That is, not expanding left to
right and no 50% growth for the JTextArea and JTable each.

Again: Thanks, everybody!

No the actual JGoodies Forms Library (forms-1.0.6.jar) is only *48kb*.

The complete Forms zip download, from
http://www.jgoodies.com/downloads/libraries.html, is only *1.1MB*.

Also the last example, using gridbag from Steve, is still doing what
Oliver did earlier today in his example.. That is, not expanding left to
right and no 50% growth for the JTextArea and JTable each.

I haven't followed java app framework development closely. So some of
the stuff in the list below no longer exist or is not suited. Anyhow,
you might want to have a look at JLense, Kanabos, Pustefix, Merlin,
Jaffa, Pulpitum, JGoodies, JUICe, or Atris Framework. Oh, and both
Netbeans and Eclipse (the IDEs) do have some RCP (rich client platform).
The NetBeans Rich Client Platform and the Eclipse Rich Client Platform
respectively.

Sun is also going to standardize an app framework in JSR 296, related to
http://wiki.java.net/bin/view/Javadesktop/SwingLabs. But that will take
some time, and it will be a committee compromise.

There is also stuff like SwiXML or XUI for the XML-everywhere fanboys.

This layout manager is exactly what I've been looking for - I don't
think I'll ever use gridbaglayout again. IchBin's JGoodies solution
looks great too, but since I already spent way too much time on this, I
wanted to go with a standalone, layout manager only solution - and
since IchBin's already solved the problem with JGoodies there wasn't
any more fun to be had that way.

I still need to install eclipse and look at SWT and netBeans, and
probably the other JGoodies, but it seems at least as far as layout
managers are concerned, I'm all set.

Again: Thanks, everybody.
